Proposing to deprecate railway=razed and railway=dismantled

I’m going to BC next week for work, and part of me wanted to make some side-trips whilst I’m in the middle of proverbial nowhere to gather some boots-on-the-ground info for OSM. Now part of me also wants to get some of the contributors to this discussion thread to try to suss it all out with satellite photography, just to see what shenanigans they’ll come up with. I’ll be way up in the mountains; maybe while I’m there they’ll find Bigfoot for me.
